Hello

GL_TRIANGLES is static, you don't need an instance to use it.

Using a GLEventListener and an animator is simpler and less error prone. If you think that it would be easier to get rid of them, you'll be completely wrong, it's supported, it's doable, JogAmp's Ardor3D Continuation based on JOGL uses GLEventListener but no animator. However, I advise you to use our abstractions especially as you're a beginner, getting rid of them is allowed in order not to patronize our user base and to be flexible to support particular cases.

Maybe this example can help:
